FTTH Blog points to an interesting article on the Utopia project in Utah, something I investigated and wrote about for clients back in my pre-blog days. I would also highlight the following quote, and note that this applies even moreso to the European case, though substituting "DSLAMs" for "set of wires":
"It would be absurd for each airline to build its own airport. But that’s just what we’ve been doing for telecommunications. Qwest has its set of wires in the ground, and Comcast has its own. We think it makes sense for a city or a region to build the airport, have someone operate it, and let as many airlines provide service as want to."
